Eric was scrolling a social media channel he regularly browsed for porn. Seconds into a video, he froze.
He realised the couple he was watching - entering the room, setting down their bags, and later, having sex - was himself and his girlfriend. Three weeks earlier, they had spent the night in a hotel in Shenzhen, southern China, unaware that they were not alone.
Their most intimate moments had been captured by a camera hidden in their hotel room, and the footage made available to thousands of strangers who had logged in to the channel Eric himself used to access pornography.
